First third-party iPhone app: A shopping list

OneTrip, created by designer Neven Mrgan, will allow future iPhone users to create a simple grocery list on their device. Until the phone is released on June 29, eager shoppers can save their lists as a cookie.

The app itself is straightforward: you pick from basic categories such as "Fruit," "Veggies," "Meat and Seafood," and "Drinks," which then brings up a list of more specific items. Click an item, and it's added to your shopping list. Not mind-boggling, for sure, but it is extremely useful.

The iPhone itself won't be released until June 29, but OneTrip can save your shopping list as a cookie. Thanks to that, you can start prepping for your iPhone's first trip to the grocery store right now...if you can afford groceries, of course, after buying an iPhone.
